Concepts similarity calculation is the basis for ontology mapping. Vocabulary, meaning of the word, property and instance of concepts are the important facts when calculating concepts similarity. All the facts above are combined and a composite method is proposed to calculate concepts similarity in this paper. In order to keep the effectiveness and comprehensiveness of the method, we combine concepts...
Ontology is an explicit specification of a conceptualization. With the development of semantic Web, there are more and more ontologies. How to achieve the reusing and sharing of knowledge between ontologies has become the key to the development of semantic Web. Based on the analysis of the current technologies, a computation method of parsing the feature of concept in the ontologies and making use...
Considering structure and elements of domain ontology, and multi-granularity technique on ontology integration, an ontology integration tool for the same field is developed in this paper. Take example for two electronic ontologies, in which the structural features of OWL (Web Ontology Language) files are analyzed, from which the main information are extracted and displayed by tree structure. Through...
The World Wide Web's constant growth and transformation offers great opportunities - and poses many challenges for exploitation. In our information-exploded times, it has been a hot problem that how to improve precision and recall of the content we want to search. After analyze the limitations of traditional method, bring a semantic search forward, and mainly introduce the thought of the semantic...
Web service matchmaking is an important aspect of the Web service discovery, and some efficient matching algorithms of matchmaking services are required in a dynamic biomedical environment especially. The main shortcoming of the current approaches of publishing and discovering Web service in biomedical informatics, which are basing on WSDL and UDDI, is that lacking of much flexibility and expressiveness...
The notion of ontology is introduced to information retrieval systems and semantic Web-oriented architecture of personalized intelligent information retrieval system is presented, and hierarchical tree model of local domain ontological repository of biomedical diseases system is constructed, in which the OWL language is used to detail annotate syntax and semantics of concepts, their attributes and...
